SlopeInterceptLine2D

Creates a non-vertical line given its slope and yIntercept.

Creates a vertical line given its xIntercept.

Indicates if the line is aligned to the x-axis.

Indicates if the line is aligned to the y-axis.

The slope of the line, if isVertical this is undefined (= Double.NaN).

The x-coordinate of the x-intercept (= the point where the line intersects the x-axis). If isHorizontal there's no x-intercept and this is Double.NaN.

The y-coordinate of the y-intercept (= the point where the line intersects the y-axis). If isVertical there's no y-intercept and this is Double.NaN. The slope-intercept representation (y = mx + b) uses this intercept.

Checks if two lines coincide.

Checks if the point belongs to this line.

Checks if other is a Line2D and if it coincidesWith this one.

Finds the point belonging to the line with the given x-coordinate. Throws an UnsupportedOperationException if the line isVertical.

Solves the line equation for the given x. Throws an UnsupportedOperationException if the line isVertical.

Uses slope, yIntercept and xIntercept.

Intersects two lines.

Intersects a line and a circle. Radius must be positive. Intersection is performed by plugging the line equation in the circle equation and solving the resulting quadratic equation. Circle equation: (x - center.x)^2 + (y - center.y)^2 = r^2. Line equation: y = slope * x + yIntercept unless isVertical, x = xIntercept otherwise.

Checks if two lines are parallel.
